I have an 06 and recently noticed that my gauges pulsate after the car has been warmed up and idles at the normal 900-1000 rpms. When I give it gas it stops. It does it with the idle of the car. It drives fine. Any ideas on what this is?

 

check the alternator

should I pull and have it checked or should I just go to autozone and let them check it?

 

just get it checked

Don't take take the alternator out to test it. The entire charging system can be dynamically tested in the car.
